Appreciate the congrats for being right on radical Islamic terrorism, I don't want congrats, I want toughness & vigilance. We must be smart!

The presumptive GOP presidential nominee reveled in congratulations "for being right on radical Islamic terrorism." However, he followed up the self-congratulatory sentiment with "I don't want congrats, I want toughness and vigilance. We must be smart!"

His controversial tweet came about one hour after an initial post, offering his prayers and in which he also said America needs to be "tough, smart and vigilant."

Horrific incident in FL. Praying for all the victims & their families. When will this stop? When will we get tough, smart & vigilant?

Trump drew the ire of countless Twitter users, who didn't hesitate to share their disdain for his second tweet — regarded by many as a publicity stunt — just hours after the shooting.

@realDonaldTrump You're the only person in America who would or could "appreciate the congrats" while families mourn 50 dead.

@sacca when is America going to see what this guy really is? Frightening.

@realDonaldTrump congrats on being a joke

@realDonaldTrump You're congratulating yourself because 50 people are dead this morning in a horrific tragedy?

@realDonaldTrump you've really gotta be kidding me rn

@realDonaldTrump You're crowing about congrats because 50 people were murdered. WTF is wrong with you?

Mass shootings have historically been politicized, particularly when it comes the issue of gun control. In recent years, American Muslims haven't been immune to this process either, as their religion often becomes embroiled in the ensuing debate.

Even without evidence, any act of violence involving Muslims is quick to be labeled "terrorism," a nomenclature not so loosely afforded to crimes committed by Christians, Caucasians and people of other faiths and ethnicities.
